I think you’re asking what ‘Ne’ means. Hi, Thanks A reaction read at <18 hours may be falsely interpreted because the carbohydrate fermented may not have produced enough acid to … When the lab doesn’t know the results will be high, they don’t dilute the sample enough (as we explained above) and so, they can’t count the colonies accurately, as there are too many.
